After getting struck by lightning once, I have my ladder line grounded through its balun to a ground bar in my shack right where it enters. This will not protect from a direct strike, but it will handle nearby discharges. A direct strike will vaporize my ladder line, so there is no point in me going over the top protecting it.
At the shack subpanel, I put in an 8ft galvinzed rod connected to the panel with 8ga wire. Then from the panel it goes to a ground bar up on the wall, where all my equipment is grounded to.
The tower outside has three of these 8ft galvanized rods on it, one off of each point, all bonded together with 8ga wire. The tower's ground is seperate from the building's due to the fact I would have to cross three cables from the cable co at six inche depth.?
I am not the best to ask on this subject, but this is just what I have setup.
